Abstract
In twelve dialysis centers in Slovenija systematic monitoring of Al and some other ologoelements in tap water, water after softening, water after reverse osmosis and in dialysis fluids is going on. The sampling is performed twice per year and of dialysis concentrates periodically. If higher concentrations of oligoelements are found in dialysis fluids the reasons for their appearance are eliminated in order to ensure the noraml status again. The exposure to oligoelements is studied in dialysis patients. The results of measurements in the particular blood fractions and in bones are comapred to the content of oligoelements in spent and fresh dialysis fluids. Special care is devoted to development of analytical procedures for reliable determination of oligoelements in biological samples by flame and electrotehrmal atomic absorption spectrometry. The efficiency of various procedures for sample decomposition (acid digestion in Parr bombs, microwave digestion) is studied and the possibilities for direct determination of oligoelements in some biological samples e.g. peritoneal dialysis fluids is investigated.
